Preparation and Characterization of TiO2 Nanowires on Aluminum Substrate
Combined with sol-gel method, ultrasonic impregnation approach was employed to prepare TiO2/ Al2O3 surface composite on aluminum. The results showed that with the effect of ultrasonic, the TiO2 colloid fabricated by sol-gel method can enter the inner of the ordered AAO film to form anatase TiO2 nano wires after being heated at 500℃ for 2h. The diameters and lengths of TiO2 nano wires were controlled by the diameter and thickness of AAO film. Close to the bottom of aluminum substrate, the TiO2 nano wires became nano pipes, plates and particles.
